AUGUST BERGGREN, OF EAGLE BEND, lld'NESOTA.

Application filed December 11, 1924. No.

To all whom it may concern:

Be it known that l, r-iuetxs'r it? sensi-r, a citizen of the United States, residing at Eagle Bend, in the county of rlodd and State of Minnesota, have invented certain new and useful Improvements in Distributor Attachments to lFhrashing Machines, of which the following is a specification.

This invention relates to attachments to thrashing machines and similar separating machinery for the purpose of assisting in evenly and uniformly distributing the material as it comes from the heater cylinder or the like over the surface of the feeding devices, and for disintegrating or loosening the masses of the straw, especially when tightly compressed or 'when wet or entangled, and has for one of its objects to simplify and improve the construction and increase the efficiency of devices of this character.

Another object of the invention is to provide a device of this character which may be installed in thrashing machines and the like of various forms and makes without material structural change.V n

Vith these and other objects in view the invention consists in certain novel features of construction Vas hereinafter shown and described and then specifically pointed out in the claims, and in the drawings illustrative of the preferred embodiment of the invention.

Figure 1 is a plan view of a portion of thrashing machine frame includingv al portion of the feeding pan, with the improved attachment applied.

Figure 2 is a side elevation of the exterior of the frame disclosed `in Figure 1.

`Figure 3 is `a transverse section on the line 3-3 of Figure 1, looking in the direction of the arrow.

Figure 4: is a longitudinal section on the line %t of Figure l, looking in the direc- Jtion of the arrow.

Figure 5 is an enlarged det-ail in section on line 5-5 of Figure 1.

The improved device is designed to be located between the side walls of a thrashing machine or the like, and above the sla-tted straw rack, Iand preferably relatively close to the cylinder and its concave, and in position to operate on the grain and straw as they leave the cylinder, but as the cylinder and concave form no part ofthe present invention they are not shown.

Portions of the side walls of a tluashing machine are represented at 1 0 and 11, portionsof the supports for the grain pan at 12 and a plurality of the slats of the straw rack at 13, of the usual construction.

Mounted for rotation through the side walls 10 and 11 is a shaft 14 having means at one end, such as a gear or chain wheel 15, for rotating the same. The shaft 14e is formed with a plurality of cranks 1G directed obliquely to the longitudinal axis of the shaft. Two of the cauks are shown, but any required number may he ei'uployed, as required. Y

Aplate 17 is coupled to each of the cranks loy spaced clips 18, so that the crankswill rotate relative tothe plate and its attachments.

Attached at 19 to each plate 1? is a. bar Z0 which extends for some distance away from the crank sha-ft, as shown.

A rigid support 21 entends between the side walls 10 and 11 and is attached thereto at 22, 23.

One of the fastening devices 19 is extended and formed into a semi-globular socket 2e, and movably mounted in each socket by a globular terminal 25, is a rod 26, the upper end of cach of the rods being extended through the support 21 and movably coupledY thereto by, a nut 27 and washer 28.

A spring 29 surrounds the rod 26 and hears at its ends respectively against the socket 24e and the support 21, as shown more clearly in Figure 5.

By this arrangement as the shaft 14 is rotated by power applied to the wheel 15, the coaction of the cranks, bars and springs will cause the outerl free ends of each of the bars 20 to first move downwardly for a short dist-ance, thence laterally in one direction for a longer distance, thence upwardly for a short distance and thence laterally in the opposite direction for a relatively long distance, and cause-the mass of 1 aterial passing over the straw rack to loe effectually disintegrated or loosened and uniformly distributed over the straw rack, and disposed in the loest condition for the further act-ion of the separating operations. l

The improved device is especially efficacious upon wet and tangled masses of material.

The improved device is simple in construction, and can be inexpensively manufactured and applied to various constructions 0f thrashing,l inachines and the like, and Without interfering with the usual parts of the inachine.

he preferred einbodiinent of the invention is disclosed in the drawings and set forth in the specification, butit'ivill be understoot` 'that modifications uithin the scope of the claimed intention may be inadc in ie construction -Without departing' from the principle of the invention or sacrificing any ri its advantages.

Havino' thus described the is claimed is:

l. ln an apparatus of the class described, shaft havinpv a plur rlity of cranks directed obliquely to the ll ng; udinal axis thereof, a plate inountcd for Vlot"L l )n upon each of said cranks, a bar rigidly attached to cach of said plates, a socket device carried by each of said bars, a stationary support, a rod for each of said barsand movable at one end through said support and respectively entlie sockets of the bars at the other end, and a spring for lach of said rods and operatinp` between each of bars and said support.

2. n an apparatus ofthe class described, a shaft havingl a plurality of cranks directed obliquely to the longitudinal axis thereof, a bar rotative relative to each of said cranks, socket device carried by each of said bars, ar stationary support, a rod for each of said bars and inovable at one end through said support and respectively engaging the sockcts of the bars atv the other end, anda spring` for each of said rods and operating` between each of the bars and the supports.

3. In anapparatus of the class described, a supporting trarne includingvertical sides,

invention what a plurality of spaced raddle devices extending" tral versely of the frame, a shaft inounted for rotation through the frame sides above the line of the raddle devices and having a plurality of cranks directed obliqucly to the lono'itudinal axis of the shaft., a bar rotative to each of said cranks, a stationary support between said frame sides, a rod niovably engaged respectivelyY with each of said bars and support, and a spring` for each of saidrods and operating` bet-:veen the bars and support.

ln an apparatus of the class described, a shaft hzwing` a crank directed o-bliquely o the longitudinal axis thereof, a bar ro-V ative relative to said crank, a stationary upport, a rod inovable at one end through said supporty and Inovably` coupled at the other end to said bar, and a spring between s? d and support.

5. ln an apparatus of the class described, a shaft having;` a crank directed obliquely to the longitudinal axis thereof, a bar rotative relative 'to said crank, a stationary support, a socket device attached to said bar,

rod movable at one end through said support and niovably engaging at the other end in said socket, and spring bearing at the ends between said socket and support.

6. In an apparatus of the class described, a shaft having` a crank directed obliquely to tl e longitudinal axis thereof, a bar rotative relative to said crank, a stationary support` a rod movable one end relative to said support and movably engaging at the other end with said bar, and means for yieldably supporting said bar. i

ln testimony whereof, I atlix iny signature hereto.
